Any difficulty related to 3D Printer.

Steps to follow:

• After assembling the 3D Printer you always have to On the SMPS @ 230 Volt Only.
• The filament is not Coming out of the Nozzle:
  • Clean the Nozzle
• When filament stuck up in between the print
  • Check the gap between the nozzle and PTEF tube and clean the PTEF tube.
  • Check Extruder fan working well.
  • Or else need to replace the nozzle and Bowden tube.
• What temperature have you set for printing?
  • PLA: 210°C for the nozzle and 0°C-40°C for bed if required
  • ABS: 235°C for the nozzle and 100°C-110°C for bed
• When filament not sticking to the bed.
  • Adjust the bed manually by turning your wheel On right so it will tighten the bed it will go down. On the left, so it will loosen the bed it will go up.
  • Apply glue to your bed.
• For the Print Quality, troubleshooting guide
• Check your filament option: On or off it has to be always off. 
• Layer skipping issues
  • Check XY belts are properly tight or not.
  • Check the motor wire connections and the z-axis rod properly fix or not.
  • Also, check G-Code File or else make a new file as per specification.
• Limit switch
  • If your X, Y and Z axis not working that time check Limit Switch.
  • While doing Auto home if the extruder is hitting any axis check the limit switch.
• Heating Problem
  • First, you have to separately heat nozzle temperature and then bed temperature to understand where the error is occurring
  • When the nozzle doesn’t heat or doesn’t show temperature check your printers thermistor and heating cartridge.
• Bed
  • When the bed doesn’t heat or doesn’t show temperature check your bed thermistor.
• To update the firmware of your printer
